Weightlifting and CrossFit can be a great way to develop full-body strength. While CrossFit pays attention to mobility, it’s still easy to incur imbalances in the body—especially when you head to a desk and sit for eight hours or more right afterward. A strong but tight front body puts you at risk for both overuse injuries that come from chronic imbalance between muscle groups and acute injuries, especially to the back, as you lift or go through other daily movements.
